Wedding Budget Calculator Widget
Turn a total budget and a guest count into a category-by-category wedding plan. Default shares start from The Knot's Real Weddings Study figures for US couples, every share can be edited, and the widget shows the cost per guest, the amount for each category and anything still unallocated.

How it works
The total budget is divided by the guest count to show what each guest costs - The Knot's 2026 Real Weddings Study, covering 10,474 US couples married in 2025, reports an average of $34,000 for 117 guests, or $292 a guest. The budget is then split by percentage across eight categories. Two defaults come from The Knot's 2025 study, where couples reported spending about $8,000 on the venue alone and about $22,000 for the venue with catering, alcohol and rentals, out of a $33,000 average: so the venue starts at 24% and catering, bar and rentals at 43%, two-thirds together. The remaining shares - photo and video 10%, attire and beauty 6%, flowers and decor 6%, music 4%, other items 4%, contingency 3% - are planning assumptions. Change any share and the amounts update; shares below 100% leave an unallocated amount with a warning, and shares above 100% are refused. A table lists every category and the bar shows the five largest.
Calculation method
- Cost per guest = total budget / guests
- Category amount = total budget x category share %
- Unallocated = total budget x (100 - sum of shares) / 100; shares above 100% are refused
Worked examples
US average budget
Inputs: 34,000; 117 guests; default shares
Result: 291 per guest; venue 8,160; catering, bar and rentals 14,620; contingency 1,020
34,000 / 117 = 290.60.
Smaller venue share
Inputs: Same budget; venue 14%
Result: 3,400 unallocated (10%)
Shares now add to 90%, so a warning asks you to assign the rest.

Limitations
- Default shares are US-based and partly assumed; weddings in other countries divide budgets differently.
- Engagement rings and honeymoons are outside the budget categories.
- Gives one total per category; it does not track deposits, payments or vendor quotes.

Questions
What does the average wedding cost?
The Knot's 2026 Real Weddings Study reports an average of $34,000 for US weddings in 2025, with 117 guests and $292 per guest. Averages hide wide variation: the 2025 study found state averages ranging from about $18,000 in Utah to $57,000 in New Jersey.
Where do the default percentages come from?
Venue (24%) and venue plus catering, bar and rentals (67%) follow The Knot 2025 study, in which couples spent about $8,000 on the venue alone and about $22,000 including catering, alcohol and rentals out of $33,000. The other shares are typical planning assumptions, not survey data - edit them to match your priorities.
How do I cut the cost per guest?
Guest count is the biggest lever because catering, drinks, rentals and favours scale with it. Removing 20 guests at $292 each saves about $5,840 - more than most single-vendor savings.
Why include a contingency?
Overtime, last-minute rentals, alterations and tips are common surprises. A 3-5% contingency keeps them from coming out of another category. On a $34,000 budget, 3% is $1,020.
Does it work in other currencies?
Yes - choose any currency. The survey benchmarks are US-dollar figures for US weddings; costs and category shares differ by country, so treat the defaults as a starting point and adjust them.
